Type c Orin AGX

Can the recovery circuit be implemented with USB type-A?
or only using type-C?

You should make it as a design that at least it can support device mode through standard way.

For example, type C or micro B is able to support OTG. But type A cannot.

The device mode is required during flash process.

micro B

Hi WayneWWW, thank you for quick reply,
what is the need of type C or micro B for recovery? please see below from document “Jetson AGX Orin Series - Design Guide” :
“Recovery mode using USB 2.0 is from interface USB0_N/P only. No other signals are required or supported for entering Force Recovery mode. Neither VBUS nor ID detection is needed.”

It is actually a complicated one to explain.

From hardware aspect, you can enter recovery mode without vbus/id detection.
But if you want every NV official flash tool to work fine on your board, you must design the device mode part.

From software explanation: there are two kinds of flash tool on Jetson.

1. flash.sh : can only flash internal storage (emmc) and does not care about device mode things on your board
2. initrd flash tool : can flash both internal storage and external storage (SSD). Need to use device mode in its flash process.

thank you for explanation,
so you recommend to implement the recovery usb with micro-B/type-c connector?

[WayneWWW]

yes, either type C or micro B should be fine.

However, type C would be a more complicated case in software configuration.
